Description

The aim of this prospective randomized double-blind study is to compare the effectiveness of routine antiemetic prophylaxis for the prevention of intraoperative nausea and vomiting (IONV) in non-fasted parturients undergoing emergency cesarean section under spinal anesthesia. Nausea and vomiting are common complications during cesarean delivery performed under spinal anesthesia and may negatively affect maternal comfort and perioperative safety. The incidence of these symptoms may be particularly increased in emergency cesarean sections involving non-fasted (full-stomach) parturients. This study compares two commonly used antiemetic strategies, namely 5-hydroxytryptamine-3 (5-HT3) receptor antagonists and dopamine receptor antagonists, to determine their relative effectiveness in preventing IONV during surgery. The findings are expected to contribute to optimization of antiemetic prophylaxis protocols, improvement of maternal comfort, and reduction of perioperative complications associated with nausea and vomiting during emergency cesarean delivery.

Interventions

  • Ondansetron 4mg (Drug)
    Prophylactic intravenous administration of a 5-HT3 receptor antagonist prior to cesarean delivery under spinal anesthesia.
  • metoclopramide (Drug)
    Prophylactic intravenous administration of a dopamine receptor antagonist prior to cesarean delivery under spinal anesthesia.
